The E+E EE23 Humidity / Temperature Transmitter is designed for industrial and high-end HVAC applications. It accurately measures relative humidity and temperature and precisely calculates dew point and frost point. The device is available with wall, duct, remote, and miniature remote probe types, housed in either polycarbonate or metal enclosures.

Measurement data is available on two analog outputs (0–5/10V or 0/4–20mA), with an optional relay output for limit switching. An optional proprietary coating protects the sensing elements against corrosive and electrically conductive pollution. Field adjustment can be performed easily using push buttons, allowing for convenient on-site calibration.

Key applications include HVAC climate control, test chambers, process technology, dryers, clean rooms, greenhouses, storage rooms, and meteorology. The EE23 delivers reliable performance across its full measurement range of 0–100% RH and -40 to 180°C, ensuring accurate environmental monitoring in demanding conditions.
